This invention has reference to bowling alley con struction and aims to provide al novel l construction which will be securely braced to withstand the strain to which a bowling alley is subjected, the construction being such as to maintain the alley level at all times.

.'f Another important object of the inverntion is toV provide' an alley of thistypehavng means whereby the same may be raised or lolowered tol facilitate leveling of the \allev A during installation of the alley, or for truein g f the alley after it has been in use.

A. still `further object of the invention is to provide a bowling .alley Aconstruction Aemlbodying an all steel under vconstruction to.

render the Valley noiseless.

- 'lVith t-be foregoing and other objects in l -View which will appear asthedescription proceeds,'the invention resides in thecombination andarrangeinent of parts and in the details vof construction hereinafter described and claimed, it being understood that changesin the precise embodiment ofthe invention herein disclosed, may be made V within the scope of what is claimed, without departing from the spiritof the invention. Referringto the drawingsf Figure 1 isa plan View ofan alleycon'- structed in accordance-with the invention.V

Referring to the drawings in detail, the

taken on line Figure 9 is a perspective view ofthe ad-` 'se-riai No;v 235,014.v secured tothe surface on -which the alley is constructed, bymeans of the angle bars 6 that are provided with 4openings to receive.

the bolts 7 that secure the angle 'barsto the i supporting surface.

Anglebars 8 are`secured to the inner surface of the bars 5 and are also provided with openings to receive the securing members 9.

Bolts-10 yextend through these angle bars as well as the bars 5, to firmly secure the bars 5 in their upright positions.

'- Disposed in parallelrelation with the bars 5 are bars 11 that are secured to the supporting surface by means of the angle bars '12.

Connecting the inner bars 11 and disposed transversely of the alley`proper, are supporting bars 13 which are of channel bar con-i struction and arranged in pairs asshown by Figure 6 of the drawings, the bars of'each pair being held in spaced relation by means of the filling timbers 14 and 14.

'Phe memberlt is 1n the yform of `a loose 'filler which lowers and covers opening 48 to l prevent sound from travelingfthrough openings 48 as alley is raised.

At the ends of thebars 13 are angle dbars l 15 which are secured to the bars 13 b means 'of bolts 16, there being provided olts 17 extending through the vertical flanges of the angle bars 15 for securing th`e angle bars'l tothe bars 11, the bars being provided with elongated openings 18 for the reception of these bolts 17, to the end'that the angle bars. 1 5 aswell as the transverse supporting bars 13 may be adjusted vertically to level the alleys and on which the alley timbers may rest in the formation ofthe alley.

Supported between each pair of bars 13 and disposed adjacent to the outer ends thereof, are the adjusting screws 19 that are mounted'in bearings 20 secured to the inner surfaces ofthe 'bars 11, the threaded adjusting screws 19, 1;operating in threaded bearing members 21,"t'o the end that as the adjusting screws 19 are operated, thevbars 13 will be raised or lowered, at'the will of the operator, it being understood that the bearing members 21 are secured to both of the bars 13 as at 22.

Openings 23 are provided in the periphery of the adjusting wheel 'or disk that is 24 extend through openings in the bars 11, Y

it will be obvious that the wheels or disks 24 bearagainst the lower edges of the openings when the wheels or dislrs are rotated to raisethe supporting hars 13.

Openings 25 are provided in the upper surfacev of the wheel 24 and are designed to accommodate the pin 26 that passesA through j the keeper 2T that is formed with an' opening to receive the pin, with the result that after the wheel" has been adjusted, the pin may he inserted to secure the wheel against movement. v

Between the pairs of bars 13 and secured to the bars 11 by means ot angle hars 28, are transverse bracing bars 29 which are also formed of channel bar material defining a flange 30 and holding bars 11 at a given distance apart.`

The bars 5 and 11 at each side of the alley are held in4 spaced relation `with each other by means of the channel irons'31 that are arranged in pairs throughout the lengths of the hars 5 and 11, the channel irons of each .pair being supported in spaced relation witheach other. s

These channel irons 31 provide supports for the bars 32 which are of various types and have their 'upper edges beveled so that they define a curved surface for the reception of the balls which are used in-bowling so that theballs may run to the pit at the rear end of the alley should they pass laterally from the alley proper,

rlrarisver-se angle bars 33 extend transversely of the pit and are disposed helow'the upper edges of the bars 11 that extend into the pit, the bars being covered by a metallic sheet vmaterial indicated at 34, which is covered with iberboard or similar material,the

iiberhoard and plate being provided with openings so that foreign matter such as and dust may fall therethrough.

Angle 'oars indicated at 35 areprovided and have downwardly extended forward end portions 36 connected with the hars 5` at the rear ends thereof, the angle hars extending rearwardly as at 37 where they connect with the vertical angle bars 38, the same heing secured by means of the transverse bar 39 that connects the angle hars at each side of the alley proper.

Metallic members 40 are secured to the angle bars 35 and 38, the same being provided with openings to receive bolts 'for securing the usual 'padded material to the Vwalls et the pit for cushiondirt was,

' contact therewith.

`formed of sheet metal` ing the blows of the ballsv and pins which At the ends of the cross hars 13 are angle hars 41 which are secured to bar 11 by means or` the bolts 42 so that the cross bars 13 are held in vertical position but at the same time allowing for free movement et the hars 13 when they are being raised or lowered.

The members 43 and 46 and supporting bars 32 together with the spacing membersl 43 and 11 at the iront and rear ends of the alley are provided with small openings to receive the pithoard cushions. The angle bars 44 and 45 at each end of the alley are bolted to the angle hars 15 and are used to support alley timbers at the extreme end.

From the foregoing it will be seen-that dueto thisv construction, an exceptionally rigid bowling alley is provided, novel means Abeing used Jfor leveling the alley. lt will further he noted that owing to the fact that the deviceipresents an all steel under construction, the alley will he practically noiseless and the structureV will have a greater resale value.

I claim:

1. A bowling alley construction including ,a pair of substantially wideA spaced stationary side bars having elongated openings and forming the sides of the alley, an alley base including wide vertically movable transverse supporting bars to which the alley planks are secured, 'angle hars connecting the movable supporting bars, bolts extending through the angle bars and elongated openings to adjustably connect the alley base to the stationary side bars, and means for moving the alley base vertically.

V2. A, bowling alley construction including a pair. of substantially wide spaced stationary side bars, an alley hase including substantially wide transverse supporting hars to which alleyv planks are Isecured, threaded bearings on the transverse bars, threaded shafts extending into the threaded bearings to adjust the alley hase vertically, adjusting wheels on the lower ends of the shafts to adjust the shafts, and said wide spaced stationary side hars having slots through which ,the adjusting wheels extend to permit the adjusting wheels to be operated to adjust the alley base, and means for holding the alley base in its positions of adjustment, said means including keepers adapted to engagesaid adjusting wheel and prevent rotation thereof.

ln testimony that I claim the foregoing as i my own, l have hereto--alh'xed my signature.
